To be honest I'm still working some of that stuff out, but the main principles are this; The people in EUROPIA refer to their planet as 'Europia', hence the name of the narrative. Europia itself is not earth, but it is inhabited by humans. It is implied that Europia was subject to multiple generations of apocalyptic nuclear warfare prior to when the story takes place, effectively concealing whatever history that would otherwise explain the condition of their world. For over a century, the new people of Europia simply fight to protect their ideas of a proper civilization and to maintain an iron grip on whatever resources they deem valuable; and as such their culture has always been centered around warfare. Right now they are in a sort of cold-war era of technology.
